An audit of assessment and reporting by Approved Social Workers (ASWs)

This paper examines the routine practice of Approved Social Workers (ASWs) in adult mental health services in Northern Ireland. It begins with a review of existing literature on the ASW role before describing how a retrospective audit, using a mixed methods approach, was used to collect data on eighty-four assessments carried out to determine whether compulsory admission to hospital was needed. Respondents were also asked to consider how such assessments might be affected by proposed changes to the law in this field. The key findings highlighted a number of areas of practice that may be improved. There were inconsistencies in how the assessments were recorded and an uneven distribution of workloads across ASWs. Some problems were identified with interagency working and, in a quarter of the assessments, the ASW reported having felt afraid or at risk. The authors make a number of recommendations, which include: the use of a standard reporting procedure; that organisations should consider how to deliver a more even distribution of ASW workload; that protocols should be developed that ensure that ASWs are not left alone in potentially risky situations; and that joint assessments with General Practitioners should be required, rather than just recommended.

Imperfect assessment and limited information preclude optimal strategies in male-male fights in the orb-weaving spider Metellina mengei

Agonistic behaviour between male orb-web spiders Metellina mengei competing for access to female webs was examined in field experiments to test the major predictions of game theory. Winners of fights were significantly larger than losers, particularly with respect to the length of the first pair of legs, which are sexually dimorphic in this species and used extensively in agonistic encounters. The size of the winning male had no influence on contest intensity or duration, and neither did relative size. However, fight intensity and duration were both positively correlated with the size of the losing male. Resident males won significantly more contests than intruders. Winning intruders were significantly larger than winning residents and it was these winning intruders that tended to produce the longer fights. Female weight and hence reproductive value had a marked influence on fight intensity and duration of fights won by the intruder but not those won by the resident. This indicates that only the resident obtains information about the female. These data are discussed with reference to the discrepancy with theory and a failure of some contestants to obtain information on resource value and relative contestant size necessary to optimize fight strategy.

Discovery and Evaluation of BMS-708163, a Potent, Selective and Orally Bioavailable gamma-Secretase Inhibitor

During the course of our research efforts to develop a potent and selective gamma-secretase inhibitor for the treatment of Alzheimer's disease, we investigated a series of carboxamide-substituted sulfonamides. Optimization based on potency, Notch/amyloid-beta precursor protein selectivity, and brain efficacy after oral dosing led to the discovery of 4 (BMS-708163). Compound 4 is a potent inhibitor of gamma-secretase (A beta 40 IC50 = 0.30 nM), demonstrating a 193-fold selectivity against Notch. Oral administration of 4 significantly reduced A beta 40 levels for sustained periods in brain, plasma, and cerebrospinal fluid in rats and dogs.

Preliminary Development and Evaluation of Fiber-Optic Chemical Sensors

This paper could be consider seminal in the Civil Engineering field as it describes the first application of these sensors to a complex durability and management issue. For this reason it is potentially controversial as it requires Civil Engineers to re-evaluate the nature and scale of durability testing.
